MEASUREMENT
Fig. Fig. Fig.
For accurate measurements, follow the procedure described below.
①In cross section perpendicular to the axis of the bore, as shown in Figure 1, position the gauge along diameter ⓐ. This is the
maximum distance, and at this point the Indicator will read the maximum value. The Guide will automatically position the
Measurement Head to diameter ⓐ when inserted.
②In cross section parallel to to the axis of the bore through diameter ⓐ, position the indicator to minimize the distance ⓑ. (Figure 2)
In this position the Indicator will read the minimum value. This position must be manually determined by pivoting the Gauge as
shown in Figure 3 while watching the Indicator to find the minimum value.
OPERATION
①Before use, please make sure the Measurement Head components are not loose and tighten if necessary.
②Clean the Measurement Head and the ID of a Ring Gauge Standard using parts cleaner or cleaning solution.
③Press the [ZERO/ON] Button to turn on power. ※ A long press to the [ZERO/ON] Button will turn power off.
ABSOLUTE MODE (ABS)
Turn on power. If the “ ” or “
※ Measure absolute dimension of workpiece
” symbols are displayed on the LCD, press the [MIN] Button to turn off.
Adjust the “SET” value of the Bore Gauge to match the ID of the Ring Gauge Standard. Press and hold the [ABS/SET] Button until
“SET” blinks on the display.
Continue holding the [ABS/SET] Button and the display character to the left will blink. Use a short press of the [ABS/SET] Button to
change the value, and a long press to change the character being modified. Repeat this process to enter the dimension of the Ring
Gauge Standard on the LCD display. (Figure 4)
When the value is entered the flashing position will return to “SET”. A short
press of the [ABS/SET] Button to turn off the flashing.

Insert the Measurement Head into the Ring Gauge Standard and press
the [MIN] Button to put the Indicator into minimum-mode. Slowly pivot
the gauge (Figure 3) to display the minimum value.
Remove the gauge from the Ring Gauge and press the [CAL] button
until “OK” is momentarily displayed. Preparation for measurement is
now complete.
Put the gauge into the workpiece to be measured, and pivot the gauge
slowly. (Figure 3) The LCD will display the measured value. (Figure 5)
※Press the [ON/ZERO] Button momentarily to reset display in
preparation to measure the next workpiece.
COMPARATIVE MEASUREMENTS
Difference between workpiece and reference
Turn on power. If “ ” or “ ” symbols are displayed on the LCD,
press the [MIN] Button to turn off. If “ABS” is displayed press the
[ABS/SET] Button to turn off.
Insert the Measurement Head into the Ring Gauge Standard and press
[MIN] Button to put the Indicator into minimum-mode. Slowly pivot the
gauge (Figure 3) to display the minimum value.
Remove the gauge from the Ring Gauge and press the [CAL] button
until “OK” is momentarily displayed.
Preparation for measurement is now complete.
Put the gauge into the workpiece to be measured, and pivot the gauge
slowly. (Figure 3) The LCD will display the difference between the
measured workpiece and the calibration standard. (Figure 6)
Press the [ON/ZERO] Button momentarily to reset display in preparation
to measure the next workpiece.
